Research paperExperimental CharacterizationRoom-temperature quantum emission from interface excitons in mixed-dimensional heterostructuresN. Fang, Y. R. Chang, S. Fujii, D. Yamashita et al.arXiv·2023·10.1038/s41467-024-47099-6·arXiv:2307.15399AbstractWe report room-temperature observation of interface excitons in mixed-dimensional heterostructures consisting of two-dimensional tungsten diselenide and one-dimensional carbon nanotubes. Bright emission peaks originating from the interface are identified, spanning a broad energy range within the telecommunication wavelengths. The effect of band alignment is investigated by systematically varying the nanotube bandgap, and we assign the new peaks to interface excitons as they only appear in type-II heterostructures. Room-temperature localization of low-energy interface excitons is indicated by extended lifetimes as well as small excitation saturation powers, and photon correlation measurements confirm single-photon emission.Read more
